STEAM HEATED RADIATOR Robert Henri Mautsch, Brussels, Belgium, assignor to The Westinghouse Air Brake Company, Wilmerding, Pa., a. corporation of Pennsylvania Application November 17,1931, Serial No. 575,512 In Great Britain November 18, 1930 1 Claim. (01. 257-159) This invention relates to steam heating appansion and at its end within the regulating head paratus for railway vehicles and other purposes 1 carries a flanged guide element 14 which is of. the kind in which the radiator of the apparasecured to one end of a cylindrical corrugated eletus is provided with a thermostatically operated ment composed of sheet copper or other suitable regulating mechanism for automatically controlmetal forming a bellows element 15, the other end 60 ling the supply of steam to the radiator. of which is secured at 16 by a steam tight joint to The invention has for its object to provide an the interior of the head 1. A spring 17 located improved construction of apparatus of this charwithin the bellows element tends to move the acter which shall be relatively light in weight, inguide element 14 together with the regulating rod expensive to manufacture and efiicient, accurate l3 and valve element '7 towards the left, and the 5 and reliable in operation. guide element 14 is engaged by the inner end of Another object of the invention is to provide a screw-threaded sleeve 18 mounted in a correa radiator having two heads connected together spondingly screw-threaded aperture in the head by tubular elements and means for venting air 1 and provided at its outer end with an operating from the chamber in one head to an outlet assoelement 19. 70V ciated with the other head. The extreme end of the regulating head 1 is The features of the invention involving therprovided with an adjustable collar 20 having a lug mostatic control of the radiator have been in- 21 adapted to co-operate with 2. lug 22 provided cluded in a division of this application, Serial on the operating element 19 and serve as a stop 20 No. 663,149, filed March 28, 1933. for the latter, the collar 20 being adapted to be 75 In order that the invention may be clearly secured with the lug 21 in any required position understood a preferred form of construction of by means of a screw 23. radiator embodying the invention will now be The chamber 12 in the control head 2 is prodescribed, by way of example with reference to vided with an outlet 24 for water of condensa- 25 the accompanying drawings, in which:-- tion, this outlet being, if desired, connected to an so Figure 1 is a sectional View, on the line II outlet or drain pipe, and a tube 25 extending of Figure 2 of the improved radiator. through the tubular element 5 from a chamber Figure 2 is a sectional view on the line II-II 26 in the regulating head to the outlet 24 in the of Figure 1. control head serves to conduct air from the cham- 30 Figures 3 and 4 are end views of the radiator ber 26 to the outlet 24 when steam is supplied 5 looking towards the left and right respectively to the inlet pipe connection 9.

Referring now to the drawings, the radiator The operation of the apparatus is as follows:-

body comprises two hollow end portions or heads The operating element 19 can be set into one 1 and 2 cross-connected by a number of tubular or other of a number of different positions corelements 3, 4, and 5 and 6 composed of copper responding for instance to hot, moderate or other suitable metal havingahigh temperature and cold. In Figures 1 and 2 it is shown in co-efficient of expansion, the ends of these tubuits extreme position (hot), this position being 40 lar elements being secured in the heads 1 and 2 defined by the lug or stop 21 on the collar 20, in any suitable manner which will provide steam which can be moved into any required position tight joints. The head2 termed the control head with respect to the regulating head 1 and recontains the steam inlet valve element 7 adapted tained therein by means of the screw 23 so as to cooperate with a suitable valve seat 8 and concorrespondingly to define the extreme position of 5 trol the passage of steam from an inlet pipe conthe operating element 19.

The With the operating element set in an interregulating rod 13 is composed of a metal having mediate or moderate position the regulating 55 a relatively low temperature co-efilcient of exrod 13 is moved towards the right (Figures 1 and 2) with the result that the valve element '7 is moved away from its seat 8 and permits the inlet of steam into the internal chamber 12 of the control head and thence into the tubular elements 3, 4, 5 and 6. The latter will thereby be heated and owing to their expansion tend to move the regulating head 1, which is arranged to be free to move, away from the control head 2, which is fixed, this expansion causing the valve element 7 to re-engage the seat 8 and thereby prevent the further admission of steam as soon as the radiator has attained a corresponding temperature. Q

A similar action occurs when the operating element 19 is adjusted to its hot position (Figures 1 and 2), the admission of steam past the valve element 7 to the tubular elements 3, 4, 5 and 6 being, however continued until the radiator has attained a correspondingly higher temperature so that the tubular elements have expanded to a greater extent. The tubular elements 3, 4, 5 and 6 are as shown in the drawings provided with radiating fins 27 and it will outlet at the other chamber.
